debian apt packages hash sum mismatch [closed]

Question 1

Try using apt-get:

apt-get clean
rm -rf /var/lib/apt/lists/*
apt-get clean
apt-get update
apt-get upgrade

Question 2

If deleting /var/lib/apt/lists/* does not work...
(esp. if you're behind a proxy), fix "Hash Sum Mismatch" like this:

Create file /etc/apt/apt.conf.d/99fixbadproxy
with this content

Acquire::http::Pipeline-Depth 0;
Acquire::http::No-Cache true;
Acquire::BrokenProxy    true;

EDIT: My ubuntu installation has crashed. I am not sure about the exact reason, but this hack is the prime suspect.

I faced a similar issue

Fortunately, the hash mismatch occurred only for one package. Since I was absolutely sure that the package that got downloaded was the intended one, I simply edited out the InRelease file.

The steps I followed: 1. grep for the expected has in /var/lib/apt/lists

sudo grep 46924d3fdb329b18b652bc3410f1f2c92ef1259b9a7d66bb1c5d3804b42a8c1c *

In my case it was

in.archive.ubuntu.com_ubuntu_dists_artful_main_binary-amd64_Packages
Replaced the hash values of expected file with the hash values of received file.
The upgrade went through.

Question 6

Replace your /etc/apt/sources.list with:

deb http://http.debian.net/debian/ jessie main
deb http://http.debian.net/debian/ jessie-backports main
deb http://security.debian.org/ jessie/updates main

Then I'd also run:

sudo apt-key update -y
sudo apt-get update -y
sudo apt-get upgrade -y

That should do the trick.

Question 7

Upgrade apt with sudo apt-get install apt

Question 8

In my case the following solution didn't work for me:

/var/lib/apt/lists/*
Changing servers to "principal server" (or some other foreing server)

I still was having the same repository giving me the "Hash sum mismatch" error.

I solved trying this solution:

go to "Software & updates"
Uncheck all repositories from the "Ubuntu Software" section
Select the "Autentication" section
Delete all entries
Make a sudo apt update (with no repositories it sould end very soon)
re-open "Software & Updates" -> "Ubuntu Software" and re-check al your needed repositories
try again with sudo apt update

Good luck.

Question 9

sometime reverse proxy(apache,nginx,...) and network will make checksum issue, we can try http proxy of different region to solve the problem:

apt-get update -o Acquire::http::Proxy="$HTTP_PROXY"  -o Debug::Acquire::http=true

Question 10

In my case it was trying to install Nodejs from nodesource that got really problematic always ending up with: "hash sum mismatch". None of the above solutions worked.

I couldn't understand why since I was following the instructions to the letter:

# Using Debian, as root 
curl -sL nodesource-url | bash - 
apt-get install -y nodejs

Turns out that the repositories for Nodejs used https when my main debian sources.list was using http.

cat /etc/apt/sources.list.d/nodesource.list

deb     https://...
deb-src https://...

Changing the URLs to http and running apt-get update solved the problem.

Question 11

For me, rm -rf /var/lib/apt/lists/* && apt-get update didn't work.
However, rm -rf /var/lib/apt/lists/* && apt update did work.
